After a couple of hours last night and some this morning I've got my first PC build up and going. I downloaded the P5B Probe software for my P5B mobo and it says that the motherboard is running a bit hot. I did a little bit of a google search and came across someone saying that the case needs another fan or maybe that Vista runs video settings high. However, my CPU is runing at a smooth low temp. So I was wondering....does the mobo run hot just for a little while? Is 49 degrees Celsius too hot? The threshhold or the point that the Probe sofware reccomends is 45. I plan on gaming should I be concernced for this little guy of mine?
